Like when you say it over heats how hot are you talking? And the next cheapest item to do is if you think it is the Thermostat, change it. Are you loosing antifreeze or have you had to add any?

My 2001 Mercedes Benz ML430 heat up when it does I turn the car off get hot heat it gets cooler what do you think the problem could be I change the thermostat and the water pump is ok

Or a Air pocket, it happens when you fill coolant to fast, run the car with coolant cap off to see if is going down, your thermostat required to reach a certain temperature to open up..hope this helps before you go spend a bunch a money, it could as simple ad bleeding the coolant system..

No heat in a 2007 Altima blows only when you are on the gas

Your present thermostat seems to be stuck in the open position and not allowing coolant to warm to temperature. I think you should have your thermostat changed. This will give you heat. GOO LUCK FRIEND.

Trying to burp cooling system, but when car heats up the coolant shoots out of the radiator like a fountain.. Thermostat is removed, still heats up

You are correct in your suspicions.
The thermostat blocks flow thru the radiator to help the engine warm up. The coolant still flows thru the block with the thermostat closed. If you remove the thermostat the cooling system should flow thru the radiator and stay below 160 degrees if the air temp is below 90.
If the thermostat is out and the engine is getting hot at idle speed, either the water pump has failed, or there is another blockage in the engine block.

My van has poor heat and changed antifreeze and temp hand stopprd working does that effect heat the temp sending unit

the sending unit will not affect heat but if its broken it will effect the fuel control by giving computer false info, i dont think theres a problem with the temp unit, i think the thermostant is bad and is stuck open or you are very low on coolant, if the thermostat was stuck open then you would get some heat not very hot and would take a long time to get heat. i would start by replacing the thermostat, it is very important to bleed air from system after coolant change or thermostat replacing, after filling run engine until fan turns on , let cool some to release preasure then remove cap start engine and top off, drive for 15min then park let cool and recheck coolant, hope this helps,

Hi, My z3 heater only blows out cold air. on the

It doesn't sound like that, could be heater controls, heater core, blockage in the coolant passages or even the thermostat. Thats the cheapest solution, but if the thermostat is bad your car would not circulate coolant and would be overheating, it could be intermittantly opening too.. But they are not hard to replace if you can get to it..

The colder the weather the less heat I get from the heater. During really cold weather it will not heat-up at all. During the summer there is lots of heat. The only way I can get the tempature hand to go...

First check your antifreeze level - especially if your car is equipped with the 3.4L engine. these are known for coolant leaks due to failed intake manifold gaskets. Coolant levels that are slightly low can cause poor circulation through the heater core and can "fool" your gauge sending unit into "thinking" that the temp is low when the engine is actually on the verge of overheating.

If the coolant level is OK when you check it, replace the thermostat.

VW jetta over heating after new thermostat installed

there could be an air gap in you coolant circuit, make sure you have purged the entire cooling system of air that might have been be trapped in the cooling circuit when you changed the T-stat.

Coolant doesn't heat up!

the temp sensor just tells you the temp of the coolant and it controlls the coolant fan to turn on and off at a certain temperature........have you check for coolant leeaks???
